 We rely on a few different models for supernovae from [[https://github.com/sncosmo/sncosmo|sncosmo]]. For example, the nugent-hyper model [[https://arxiv.org/pdf/astro-ph/0403450|(Levan et al. 2005)]] used for SN Ib/c supernovae with the stretch and scale set to match the intrinsic (dereddened, rest frame) -band luminosity of SN 1998bw at maximum light. The main free parameter is the absolute magnitude. We rely on a few different models for supernovae from [[https://github.com/sncosmo/sncosmo|sncosmo]].

 +Some models are analytic / semi-analytic that can be sampled, others rely on sampling from a grid of modeled light curves through the use of Principle Component Analysis (PCA) and an interpolation scheme (either Gaussian process modeling or neural networks). Further information on model training can be found [[https://enlil.gw.physik.uni-potsdam.de/dokuwiki/doku.php?id=model_grids|here]]
